Example code in "Adding a Child View Controller to Your Content" is a bit complicated and not 100% correct

Summary:

The step N2 in documentation says  -
“2. Add the child’s root view to your container’s view hierarchy.”

But the code shows this( which is not correct example): 
   [self.view addSubview:self.currentClientView];

It should be like this:
   [self.view addSubview: content.view];

Full Code.
Code Now
- (void) displayContentController: (UIViewController*) content {
   [self addChildViewController:content];
   content.view.frame = [self frameForContentController];
   [self.view addSubview:self.currentClientView];
   [content didMoveToParentViewController:self];
}

Correct code
- (void) displayContentController: (UIViewController*) content {
   [self addChildViewController:content];
   content.view.frame = [self frameForContentController];
   [self.view addSubview: content.view];
   [content didMoveToParentViewController:self];
}
